TO 107w? Z/ M means of a rod 4 with the platform. A red Be it known that I, CHARLEs SoNNIcHsEN, 5 is suspended from the beam 3 and has a disk a citizen of the United States, residing at 6 thereon for supportingasuitable number of North San Diego, in the county of San Diego weights 7. An arm 8 extends laterally from 5 and State of California, have invented new the standard 2 and under the scale-beam 3,

This rack meshes with a gear 15, having in connection with platform-scales and which a stem 16, which is revolubly mounted in the will accurately count the number of weighing front face 17 of the casing and has an index 5 operations and the total weight of all articles 18 secured thereto. A disk 19 is also secured weighed upon it. to the stem 16 and rotates therewith, and se- Afurther object is to provide a device which cured to this disk is a spring-pressed pawl 20, will automatically indicate the weight of each which normally engages a ratchet-wheel 21, article placed upon the scales. loosely mounted upon the stem 16. Secured 20 With the above and other objects in view to this ratchet-wheel and revoluble therewith the invention consists in providing an arm is a gear 22, which meshes with a larger gear upon which are arranged casings, one of which 23, having an index 24 connected thereto and is provided with a series of revoluble disks revoluble therewith. A small gear 25 is sehaving numerals arranged thereon, and these cured to and rotates with the gear 23 and is 5 disks are driven by suitable mechanism conadapted to mesh with a second gear 23, to nected to the scale-beam and are adapted to which is secured an index and a small gear, accurately indicate the total amount weighed as above described. A train of these gears is during two or more weighing operations. provided, and located in rear of each index 24 The apparatus in this casing also serves to acis a disk 26, having numerals arranged thereon 0 curately indicate visually the weight upon the successively, these numerals preferably rang- 8o scales during each weighing operation. The ing from 1 to 10. If desired, a springarm also serves to support a counter of any pressed pawl 27 may be pivoted upon the face suitable form which is designed to count the 17 of the casing 14 and engage the ratchetnumber of weighing operations during a given wheel 21, so as to prevent the same from re- 3 5 period. turning to its normal position after a weigh- 5 The invention also consists in the novel coning operation. Any suitable means, such as struction and arrangement of the several parts, a spring 13 may be employed for retarding which will be more fully hereinafter described the rotation of the gear 15 and the movement and claimed, and illustrated inthe accompanyof the rack 13. Mounted on the arm adja- 40 ing drawings, in which cent the casing 14 is a counter 28 of any suit- 9 Figure 1 is an elevation of my improvedatable construction and having a plunger 29 tachment applied to platform-scales. Fig. 2 projecting from the top thereof and adapted is an enlarged elevation of the mechanism of to be contacted and depressed by the scalethe calculating device, some of the gears therebeam 3. 45 on being shown in dotted lines. Fig. 3 is a WVhen an object to be weighed is placed section on line 3 3, Fig. 2. upon the platform 1, the outer end of the 2 Referring to the figures by numerals of refscale-beam 3 will be raised, as is obvious, and erence, 1 is the platform of the scales, adjathe lever 10, connected thereto, will draw the cent which is a standard 2, having a graduated link 12 and the rack 13 downward. The gear 5' beam 3 fulcrumed therein and connected by 15 will therefore be rotated and will carry 1 0 the index 18 therewith, and this index will point to any one of a series of graduations arranged upon the face of the casing 14: and will accurately indicate the weight of the object upon the platform. As the disk 19 rotates with the stem, it is obvious that the pawl 20 will cause the ratchet-wheel 21 to rotate therewith also and the gear 22 will partly turn the gears 23 and move the indexes 2 L proper distances to indicate upon the disks 26 the weight of the object upon the platform. The

downward movement of the scale-beam 3 dur ing its operation will depress the plunger 29, and the counter connected thereto will indicate that one weighing operation has been performed. WVhen the object has been re moved from the platform 1, the parts will return to their normal positions, with the exception of the gears 22 and 23 and the ratchet- Wheel 21. The pawl 20 will slip backward over the teeth of the ratchet-wheel, and the index 18 will move back to its normal position. I/Vhen another object is placed upon the platform, the operation above described will be repeated. If desired, the return of the index 18 to its normalposition after a weighing operation can be prevented by placing the pawl 27 in engagement with the ratchetwheel 21. It will be understood that each weighing operation will rotate the indexes 24, so that at the completion thereof the sum indicated thereby will equal the total weights of the objects weighed. The attachment can be readily disconnected from the scales by de taching the link 11 from the disk 6, and said scales can then be used independently of the indicating mechanism by the use of the weights 7.

The scales can be used without the weights 7; but where the weights 7 are used in connection with the indicating apparatus the beam 3 is weighted, so as to counterbalance a load slightly less than the average, and the indexes 18 and 24 will accurately indicate the remaining weight of the load.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described the'invention, what is claimed as new is- 1. In a device of the character described, the combination with a standard having an arm thereon and a scale-beam fulcrumed within the standard, of a casing arranged upon the arm, a train of gears therein, each gear having an index, a stem revolubly mounted Within the first gear of the train, a ratchet-wheel loosely mounted upon the stem and connected to said first gear, a pawl connected to the stem and normally engaging the ratchet-wheel, an index and a gear secured to the stem, a rack engaging the last-mentioned gear, a rod depending from the scale-beam, a hanger de pending from the arm, a lever fulcrumed in the hanger, and link connections between the lever and the rod and rack respectively.

2. In a device of the character described, the combination with a standard having an arm thereon, of a scale-beam fulcrumed within the standard, a counter upon the arm and adapted to be operated by the scale-beam, a casing on the arm, a train of gears within the casing, each gear having an index, means for preventing the rotation of the gears in one direction, a stem revolubly mounted in the first gear of the train, an index and a gear secured thereto, a rack engaging the last-mentioned gear, a hanger depending from the arm, a lever, fulcrumedthereon, and rods and links connecting the lever with the rack and scalebeam.

In testimony whereof I affix my signature in presence of two witnesses.
